Westport-Clatskanie Macadam

On the Clatskanie-Westport Section, which extended from Clatskanie to the Clatsop County Line, the work was handled originally by the Warren Construction Company, on a cost plus ten per cent. basis. The State Highway Department took this work over December 26, 1917, and from that time on the work was handled by this Department. This work consisted of 8.62 miles of sixteen-foot waterbound macadam.

On this section the costs show that the Warren Construction Company laid crushed rock slightly cheaper than the State. However, the State did all the finishing on this section, which is more expensive than laying the base rock and it was necessary to raise the wages twenty-five per cent.

after the work was taken over by the Department. C. L. Grutze was resident engineer on this work.

Clatskanie-Delena Macadam

The section extending from a point three miles east of Clatskanie to a point two and one-half miles east of Delena, known as the Clatskanie-Delena Section, was completed by L. O. Herrold on a basis of cost plus ten per cent. This work consisted of eleven miles of sixteen foot waterbound macadam, one and one-tenth miles of nine foot waterbound macadam and all necessary grading, drainage, etc. The foundation on part of this section was very poor and 10,233 cubic yards of rubble base was used in order to make satisfactory foundation for macadam. While this increased the cost of the macadam, it was the only way in which a permanent foundation could be secured on this section. P. M. Hall-Lewis was resident engineer on this work.

Delena-Goble Macadam

Clark & Dibble of Rainier contracted with the Highway Department to construct five and seven-tenths miles of broken stone macadam between Delena and Goble. The prices at which this work was taken by the contractors was very low, and the result was that almost from the first the work was handicapped by lack of proper finances. It became evident to the Department that the contractor would be unable to complete all of this work before the winter rains set in, so to facilitate matters and to provide a pa.s.sable road for the winter, the Department took over the part of the work between Rainier and Goble after about $10,000.00 worth of work had been done on this part by Clark & Dibble. The work of the Highway Department on this section is described in the article on the Rainier-Goble macadam.

Clark & Dibble successfully carried to completion the two and one-tenths miles of macadam west of Rainier. A complete statement of the costs of the work handled by the contractors is given below.

Rainier-Goble Macadam

In Columbia County the State Highway Department laid twenty-four and one-tenth miles of sixteen foot waterbound macadam and four and two-tenths miles of nine foot waterbound macadam between Goble and the Clatsop County Line. Of this the Rainier-Goble Section was taken over from the contractors, Clark & Dibble, after being partly completed. This was done in order to facilitate the work and get the road open for traffic before the rainy season.

While the work done by the State on this section cost more per cubic yard than the contractor was originally receiving, the actual difference in cost for the job was not sufficient to justify the Department in allowing the contractor to proceed with the work which would have entailed leaving the road closed to traffic for another winter.

Goble Macadam Work

A contract was awarded to Warren Construction Company September 4, 1917, for macadamizing the Goble Cut-off on a basis of cost plus ten per cent.

Columbia County has a quarry on the old road about three-fourths of a mile west of Goble, which was equipped with complete crushing outfit and arrangements were made by the contractor for the use of this equipment and all the rock for this job was crushed and hauled from this quarry.

Work was started March 1, 1918, and completed June 25, 1918.

Engineering work was done by H. C. Compton as resident engineer under the supervision of Chas. H. Whitmore.

Goble Grading Section

A new location of the Columbia River Highway was made from a point two miles east of Goble to Goble Creek and a new concrete bridge built over Goble Creek, making a saving in distance of about one-half mile and doing away with several excessive grades, sharp curves and narrow roadbed, also a dangerous bridge and trestle across Goble Creek.

A rock cut between Goble and Goble Creek was taken out by the S. P. & S.

Ry. Co. with steam shovels and the material used by them for riprap, thus making a considerable saving to the State Highway Commission. The material for the west approach to the new bridge was obtained by blasting and barring down rock from a dangerous perpendicular cliff about 1,000 feet west of the bridge, from which large rocks had fallen onto the highway. To make the highway safe it was necessary to remove this material and by using it in the bridge approach, did away with other borrow which would have been necessary. The cliff is about 200 feet high with the highway and S. P. & S. Ry. side by side at the foot, necessitating very light shots and careful work and was completed without accident to men or interruption of traffic on the railroad.

[Ill.u.s.tration: ON THE COLUMBIA RIVER HIGHWAY NEAR GOBLE IN COLUMBIA COUNTY. GRADED AND MACADAMIZED IN 1917 AND 1918]

The material for the east approach was obtained by tr.i.m.m.i.n.g up the cut left by the railroad company.

A contract for grading the cutoff was awarded to the Warren Construction Company, August 7, 1917, and work started in July, 1917. From the east end of the section to Ruben, about one mile in length, the material was handled by teams. Rock work at Ruben and at Goble was sub-let to station men. The fill across the flat between Ruben and Goble was made from side borrow, by using a steam hoisting engine, with boom and clam sh.e.l.l bucket. This work was done in the fall and winter and the material was light loam and sand and very wet, and did not pack very solid in the fill, therefore a strip of rock sixteen feet wide and one foot in thickness, taken from the rock cuts at either end, was placed on the fill and rolled thus making a solid base for the crushed rock macadam.
